Hi,

sorry, obviously, that was a mistake.

actually, i did this:

**********
# xm mem-max server 4096
# xm mem-set server 4096
**********


can i suppose then that this should work?

the thing is that xen doesn't complain, but both 'xen top' and the 
machine itself don't seem to show any increase in the memory.
However, it works when setting a lower value.

For example, I can create 'server' with 2048 and then go down to 1024 
and then to 2048 again, but never to a higher value. So... i guess that 
mem-hotplug works because I can go down and up, but It can never go up 
higher than the initial memory value.
that's why yesterday I was asking if that's is even possible,

I don't know if it has anything to do, but dom0 is Debian Squeeze and 
the domUs i've tried with are Debian Squeeze, Ubuntu Natty and Fedora 15.
Thanks.
